We have 3 objects Obj A,Obj B & Obj C. Obj C has Master Detail Relationship with Obj B & Obj B has Master Detail Relationship with obj A.
Obj A is the Grand Parent Object of Obj C.
What I want is to get the Count of Obj C records and display the count on Grand Parent Obj A.
Problem is I can not solve this requirement by writing an apex code as all of these 3 objects are Managed Package Custom object and I don't have access of their apex classes & Triggers.
I tried to write Process Builder but can not Use Count Function.
Can someone please tell me how can I get the count using config way or best way?
